I get the same issue with my Soundblaster Live 5.1, no sound output from mp3 files, videos, Gnome sounds, etc. It worked in Dapper Drake.
I have an onboard sound chip (CMedia PCI CMI8738) that I switch to the soundblaster in the Gnome Soundblaster, but the Soundblaster still doesn't work. The volume in alsamixer is not muted.
I can only use the microphone with the soundblaster, but that's another issue, as I can't mute it and there's a constant buzz because of this.
